2. 1. Ehrlichia in animals and humans

   Author : Anneli Bjöersdorff; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; seroprevalence; humans; animals; granulocytic; ehrlichiosis; Ehrlichia phagocytophila; tick-borne; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Abstract : Ehrlichia phagocytophila is a tick-borne pathogen of domestic animals, which has recently been acknowledged also as a human pathogen. It is a strictly intracellular bacterium, infecting granulocytes of the host, sometimes resulting in clinical disease - granulocytic ehrlichiosis - with manifestations ranging from mild flu-like conditions to severe infections with multi-organ failure and death.

4. 2. Animals and Humans : Human-animal interaction in northern Sweden during the late glacial and postglacial time

   Author : Therese Ekholm; Sabine Sten; Carl-Gösta Ojala; Ola Magnell; Uppsala universitet; []
   Keywords : Mesolithic; fauna; radiocarbon dating; northern Sweden; calcined bones; pioneers; hunter-gatherers; zooarchaeology; lithic technology; taphonomy; 8.2 k BP cold event; prey.; Archaeology; Arkeologi;

   Abstract : When the last remnant of the Weichsel glacier melted in northern Sweden, around 7000 BC, pioneer settlers entered virgin land, following their prey, which in turn followed the vegetation dispersion. Some of the settlers derived from the east and the northeast and spread from the Russian taiga, through Finland and into northern Sweden, the study area for this thesis. READ MORE

5. 3. Acute Myocardial Infarction: The Relationship between Duration of Ischaemia and Infarct Size in Humans - Assessment by MRI and SPECT

   Author : Erik Hedström; Lund Klinisk fysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Fysiologi; Physiology; humans; cardiac troponin T; creatine kinase isoenzyme MB; delayed contrast-enhanced magnetic resonance imaging; single photon emission computed tomography; myocardial perfusion; myocardial infarct size; myocardium at risk; duration of ischaemia; Kardiovaskulära systemet;

   Abstract : The effect of duration of ischaemia on final infarct size is well established in animal studies, but not fully evaluated in humans. Delayed contrast-enhanced magnetic resonance imaging (DE-MRI) can be used to distinguish between viable and non-viable myocardium and thus to quantify infarct size. READ MORE

6. 4. Regulation of bile acids by prebiotic food components : Studies in rat caecum and in serum of mice and humans

   Author : Tannaz Ghaffarzadegan; Avdelningen för livsmedel och läkemedel; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bile acids; Dietary fibre; Fat; Pectin; Guar gum; Barley; Lingonberry; Turmeric; Short-chain fatty acids; Gut microbiota; Caecum; Serum; Rat; Mice; Humans; GC-FID; UHPLC-MS;

   Abstract : Bile acids (BA) are formed from cholesterol in the liver and, apart from being part of fat digestion, they also act as signalling molecules in several health-related physiological processes. BA composition is regulated by gut microbiota as well as dietary fibre (DF) and fat in the diet. READ MORE

7. 5. Origins and Adaptation in Humans : A Case Study of Taste and Lifestyle

   Author : Agnès E. Sjöstrand; Mattias Jakobsson; Evelyne Heyer; Michael G. B. Blum; David Comas; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Evolutionary Genetics; Evolutionär genetik;

   Abstract : In this thesis, I use population genetics and statistical approaches to investigate early human demography, infer local adaptation in diverse sets of populations, and study the genetic basis for taste perception.In the first paper, I examine the genomic evidence for a severe bottleneck, which has been suggested based on paleontological and climate studies to coincide with the emergence of anatomically modern humans.
